Indexing Tree Elements

[Lee Goddard <lee.goddard@xxxxxxxxxxx>]

I have a template that is called for all instances of an element;
is it possible that it may compare its attributes with the attributes
of the previous document-tree node of the same level?  Is it possible
to index elements in such a manner?

Thanks in advance,
Lee
